Fig. 9 The implant sample
The focused 2D and 3D images of the original
tooth sample are observed by means of the digital
microscope. These images were both quantitatively
analyzed and also were evaluated in terms of the surface
roughness using the digital microscope software.
Fig. 10 and Fig. 11 represent the captured 2D image
of the tooth sample and assessed 3D image of the
tooth sample consequently.

Fig. 13 The assessment of the difference in original and
implant tooth sample using the scanned 3D image
In this experimental study, roughness measurements
of dental applications were carried out with a
stylus profilometer and a digital microscope. Measurements
were repeated for five measurement points
with 1mm intervals on an original tooth, its implant
and other three test implant samples. Each measurement
point taken from both stylus profilometer and
digital microscope represent the mean values.
Fig. 11 The assessed 3D image of the tooth sample
As a non-contact measurement method, the white light
3D scanning system (Steinbichler COMET 5) with the
advantage of measuring fragile and delicate nontechnical
objects was used to capture 3D models and
then make an assessment by measuring the difference
in three axes X, Y and Z (Fig. 12 and Fig.13).

its implant and other three test implant samples
The target is to produce the original tooth analogue
with the implant in order to fulfil successful results on
the patients. Therefore the roughness measurement as
